Academic literature on the topic 'Patins à roues alignées'

Objectifs Effectuer une revue systématique de la littérature portant sur les blessures associées à certains produits de consommation. Méthodologie Nous avons analysé 46 rapports de recherche de nature empirique et 32 rapports de surveillance du Système canadien hospitalier d'information et de recherche en prévention des traumatismes (SCHIRPT) dans le but de déterminer le nombre approximatif de blessures par année associées à chaque produit ainsi que toute tendance dans les fréquences. Nous avons également extrait des rapports les pourcentages des blessures qui ont donné lieu à une hospitalisation, qui semblaient résulter du produit lui-même et qui étaient associées à une utilisation inappropriée ou dangereuse ou à l'absence de casque. Résultats Les équipements de sport et de jeu de plein air semblent être associés aux nombres de blessures les plus élevés. Une proportion relativement importante de blessures semble résulter d'une utilisation inappropriée ou dangereuse du produit et du non-respect des mesures de sécurité requises. Conclusion Cette revue a permis de relever plusieurs sujets de préoccupation à propos des blessures associées à des produits de consommation : absence de casque lors de l'utilisation de patins à roues alignées, de traîneau, de planche à neige, de skis alpins ou de motomarine; conduite d'un véhicule tout-terrain (VTT) ou d'une motoneige avec facultés affaiblies par l'alcool; conduite d'une motoneige à une vitesse excessive; conception défectueuse de certains équipements de terrain de jeu; entreposage et utilisation non sécuritaires d'allumettes.

Suffering is an unavoidable reality in healthcare. Not only are patients and families suffering but also the clinicians who care for them. Commonly the suffering experienced by clinicians is moral in nature, in part a reflection of the increasing complexity of health care, their roles within it, and the expanding range of available interventions that challenge their moral foundations. Moral suffering is the anguish that arises occurs in response to moral adversity that challenges clinicians’ integrity: the inner harmony that arises when their essential values and commitments are aligned with their choices and actions. The sources and sequelae of moral distress, one type of moral suffering, have been documented among clinicians across specialties. Transforming their suffering will require solutions that expanded individual and system strategies. Moral resilience, the capacity of an individual to restore or sustain integrity in response to moral adversity, offers a path forward. It encompasses capacities aimed at developing self- regulation and self-awareness, buoyancy, moral efficacy, self-stewardship and ultimately personal and relational integrity. Whether it involves gradual or profound radical change clinicians have the potential to transform themselves and their clinical practice in ways that more authentically reflect their character, intentions and values. The burden of healing our healthcare system is not the sole responsibility of individuals. Clinicians and healthcare organizations must work together to transform moral suffering by cultivating the individual capacities for moral resilience and designing a new architecture to support ethical practice. Used worldwide for scalable and sustainable change, the Conscious Full Spectrum approach, offers a method to solve problems to support integrity, shift patterns that undermine moral resilience and ethical practice, and leverage the inner potential of clinicians and leaders to produce meaningful and sustainable results that benefit all.

Multibody dynamics models of a helicopter and two cycloidal rotor aircraft concepts capable of vertical take-off and landing (VTOL) are constructed. The first concept aircraft is a helicopter equipped with two lateral cycloidal rotors acting as a replacement for its tail rotor and is named the Heligyro. The other concept is named the Quadricyclogyro and is propelled exclusively by four cycloidal rotors whose axes are aligned. The autopilot algorithm is implemented as a proportional, integral, and derivative (PID) controller and is tuned using a genetic optimization algorithm directly on the multibody models. Aircraft vibration and energy requirements are monitored and fed as penalty functions to the genetic algorithm. The time-domain responses of the aircraft attempting to follow mission paths of variable complexity obtained from the literature are studied. Overall, the tuned VTOL aircraft are able to reproduce the requested routes with good accuracy if a certain speed threshold is respected.
